We show that a monetary policy rule that uses the exchange rate to stabilize the economy outperforms a Taylor rule in managing macroeconomics fluctuations and in achieving higher welfare. The differences between the rules are driven by: (i) the path of the nominal exchange rate and interest rate...

We provide a unified framework for quantifying the cross country and cross-sector interactions among trade, innovation, and knowledge diffusion. We study the effect of trade liberalization in a multi-country, multi-sector endogenous growth model in which comparative advantage and the stock of...

Countries that trade more with each other tend to have more correlated business cycles. Yet, traditional international business cycle models predict a much weaker link between trade and business cycle comovement. We propose that the international diffusion of technology through trade in...

We develop a structural framework to identify the sources of cross-state heterogeneity in response to US tariff changes. We quantify the effects of unilaterally increasing US tariffs by 25 percentage points across sectors. Welfare changes range from −0.8 percent in Oregon to 2.1 percent in...

We develop a quantitative framework to assess the cross-state implications of a U.S. trade policy change: a unilateral increase in the import tariff from 2% to 25% across all goods-producing sectors. Although the U.S. gains overall from the tariff increase, we find the impact differs starkly...

In this paper, we establish the importance of experience in international trade in reducing unmeasured trade costs and facilitating bilateral trade. We find a strong role for experience, measured in years of positive trade, for both aggregate and sectoral bilateral trade. In an augmented gravity...
